Another object of our invention residesin the provision of asignalinglmechanism for preventing collisions and accidents.

.llrIlOtllfiBE object of our invention resides in the provision of asignaling mechanism for indicating when a train isin any block sectionand thus warn the crew ofanother "train to remainwithoutthe blocksection until the said section has been cleared, or intil the trainwithin the said block section has moved out of the latter. 7

Another; object of our invention resides in the provision of signalmechanism for ing the posititerlisplay of danger and signals at theproper intervals and lVith these and 0 her objects in view, we willproceed to descriheour invent-ion wlth reference to the accompanyingdrawlngs.

Let the mimeral- 8 designatea post or st ndardf carryingthe signaloperating of our improved mechanism. This post or standard is preferablyformed in sections 9 10, 12 and .13, certain parts of the operatingmechanism being incased in the section W Q the c i n 13 carriesthe-sematk phore arm and signal lights. These two sections 10 and 18 areconnected by means of the section 12 which is ,hollow and tl'iroughwhiclrthe connection betweenthe signal-operating mechanism and thesignal properis passed. From the foregoing description it will beseenthat the different sections ofthe post or standard may be readily dsconnected for purposes oftransp ort ation.

Referring now to important features of the invention, let the numeral 14designate section or block of the railway track.

nected with the rail 16 by an electrical conductor 29; .l.he core 30 ofthe relay 23-, is provided at one extremity with :a bar .31, the saidbar formingiaswitch which is nor- One terminal of the coil27 off thisrelay is connected with thejrail 17,-of the block by an electricalconductor 28, while the other terminal of the coil is. conmally held inengagement with the con- I tacts 32' and 33, which are connected by thebar 81when-tl1e relay 23 is energized. The source of electricalenergy 2Osuppliescur- I to the relay :2 through the track rails 16 and 17 andithe connections heretofore recited. Y

1, NVl1en the relay 23 is energized, the core 30 is drawn upwardly andcarries the bar 31 therewith into engagement with the contacts 32 and33, which results in closing the circuit through a source of electricalenergy 34; Th s closed circuit may be traced as followsF-From thecontact 33 a conductor 34' leads to a pole 35, of the source ofelectrical energy, while a' conductor 36 leads from the other pole 37 ofthe source of electrical enorgy to a green or safe light 38. A conductor39 is connected with the opposite binding post of the green light'38 andleads. to a'con- .ductor 40, the said conductor 39 oining the conductor40 at point 41, from which point 41, the circuit is completed through aconductor 42, contact 32, bar 31, the contact 33 and the conductor34,flwhich is connected 1 with the pole 35 01" the source of electricalenergy 34. When the bar is in its normal or full line position in Fig.4,the circuit is closed through the green or safe-light 38,

.and'is'alsoior the time being closed through a motor 43 and-normallythrough an electromagnet 44, the electrical connections-with the motor43 being as follows :From a point 45 on the conductor 36, a conductor 46eads to a binding post 47 mounted on the motor 43, passing thencethrough-the motor I and a conductor 48 leading to a contact 49 of acircuit breaker 50.

member 51, of the circuit breaker 50, a conductor 52 leads to a terminal53 of the electro-magnet 44, from which pointthe motor circuit iscompleted through the conductors 40 and 42, the contact 32, bar 31,contact 33 and theconductor 34, to the pole35 of the.

source of electrical energy 34. The circuit is completed through thecoils of the electromagnet 44 as follows :-From a point'54 on theconductor 36'a conductor 55 leads to a terminal 56 of the saidelectromagnet, while from the opposite terminal 53 of the electromagnet,the circuit is completed through the conductor 40 and conductor 42,which is connected with the conductor 40 at point 41, to the contact 32,the bar 31, the contact 33 and the conductor 34 to the pole 35 of thesource of'e'lectrical energy 34. I

' iv In' -Fig. 4 of the drawing, we have shown a train 57,conventionally illustrated by means,

' of-whcels 58 and an axle 59, whereby the trackrailme'mbers 16 and 17are bridged by the-said train 57 and the current from the source ofelectrical energy"2O short circuited and the circuit through the coil ofthe relay 23 is broken, whereby its-core 30 is'released and the bar 31allowed to-drop awayfrom the contacts 32 and 33. When the' bar 31 isthus disengaged from the contacts 32 and 33, the circuit is brokenthrough the motor 43 andl electro-magnet 44 and thezsafe or green light39. Since thecircuit is broken'through From the contact the 'electro-magnet- 44 i in the aforesaid manner, an armature bar'GO isreleasedfrom the influence o'l 'thei magnet 44 andflthe semaphore arm 61 allowedto drop to the danger position, by virtue ofinechanism hereinafter morefully explained. Thernovement of the contact bar 31 away from thecontacts 32 and 33 results in closing the circuit'through the red ordanger light 62 in the ztollowing manner :The,current"from the. sourceof electrical energy34 passes from the pole 37,

through the conductor 36 toa point63 there- 7 tively, and we willnowproceed. to describe this mechanism. A' shaft i69 ismounted andconnects the opposite sidesj70 'and 71' of a frame work, designatedinits entirety by, the reference character 7 2, andup'onthis shaft is journaled a grooved pulley 7 3,, in the groove ofwhich one extremity of aflexible-device or chain 74is secured, as shown at 75, while itsopposite extremity -is"connected with a quadrant orsecter 7 6,;whichlatter instrumentality is connected with the semaphore.

arm 61 on they opposite side of a pivot 77 of said semaphore arm. In:viewof the foregoing recitation of the elements connecting the pulley 73with the semaphore a' r1n61, it will'be' understood that as the saidpulley is turned in the direction oflthe arrow (see Fig. 4), thesemaphore arm will be raised,

the saidpulley in'the opposite direction is relieved the semaphore, armwill fall. A large gear 77 is also journaled upon the shaft 69 and isconnected with the pulley; 73, to

turn in unison with the latter. The pulley. u

73 and the relatively large gear 77 are each mounted upon the same hub 78 and ,in ust therefore necessarily turn together; The relatively largegear 77 meshes with arelatively small gear jor pinion 79, which isthreaded upon a sleeve 8O as'shown at 81.

This sleeve 801s supported and journaled a upon a shaft 82,which latteris journaled'in the opposite side members 70 and 71 of the 7 frame work72, the said shaft 82 being coactually jourhaledwiththe sleeve 80'.Connected with'the sleeve 8O isla spider 83'upo'n the arms of which Tare ournaled i planetary gears 84, by means of journal pins 85 whichpass through the planetary'gearsf84- and the extremities of the arm ofthe; spider 83.

Surrounding these planetary gears 84, is an;

internal gear 86', supported by means of a spider 87, wlnchis journaledupon the shaft 1 105 while, when the resistance to the turning of '82.The said internal gear 86,: being'secured to the, arms of the spider bymeansofpset screws or bolts 88. I Meshing with the planetary gears 84,is a gear wheel89, the said gear wheel 89 being keyedor made fastuponthe shaft 82 to turn with the latter. Alsoinounted' upon the shaft82 and made'fasttherewith is av worm heel 90, which meshes with a worm91 formed upon a motorv shaft 92 of the motor fl? Assuming that themotor 43' isturning in the directionof the arrow,f(see Fig. l),

the worm 91, causes the worm wheel 90 to. revolve, 1n the dlrection ofthe arrow, the

worm in turn causing the-shaft 82 to revolve in .rthe same direction.L'Now since the planetarygears 84 are interposed between the internalgear wheel 86 and the gear 89- and the teeth of the planetary gears 84mesh with the teeth er the aforesaidtwo gears, the planetary gears '84willbe' caused to travel around and upon the periphery of the gear 89and carry the sleeve therew1th,-wh1le the internal geaix86'willremainstationary by virtue ofmechanism hereinafter more fully explalned.The sleeve 80 revolvesthe p1nion 7 9 which meshes with the relativelylarge gear 77, to cause thelatter to turnin the di 5 rection of thearrow (see Fig. 6). And

since the pulley 73is connected to turn in unison with. thegeary77, thesaid pulley will also revolvefin the same direction, whereby the chainvffwill be wound around the pulley land will act upon the semaphore arm61 to raised, or safety positiornthe circuit is closed through the coilsof tl1e;.electro-1nagnet 44:, 1 but, the circuit is broken thrcughtheme-tor t3asxsoonas the semaphorearm reaches the l raised position byvirtue of "mechanism which will be hereinafterfmore fully ex-;

3 plained.

raise thelatter to theupright or the position to indicatesafety.

- I WVhen the semaphore arm-qo ccupies the Attention ishere called tothe fact that during the upward movement of the semaphore arm thecircuitv is closed through both the motor 43 and the: electro-magnet44;, whereby the armature of the magnet 44 is drawn into contact withthe said electromagnet." This armature 60 1s pivotally ,mounted to theframework as shown at 93 and to its opposite extremity is ,pivotallyconnected a rod 94 as shown at To the opposite extremity of thisrod 94;,we plvotally connecttoggle arms 96 and 97 as shown at 98. -The upperextremity of, the toggle arm 96 is pivotally mounted or connected withthe frame work as shown at 99, the said arm having an extension 100,beyond-the I pivot- 99, adapted to be engaged by the lug 101 of an arm 102, cneextremity of which is also pivoted at 99,;While it s-opposite eX-tremity is pivotally connectedj with acollar fa g vernor 10 a, Th ,.-tgg1 l arm 7..

is pivota-lly connected as shown at @105 toione extremity ofa hand brake106. This hand brake surrounds the internal gear 86 and'tits ripheryofthe internal gear 86 is provided. The opposite extremityof thishandbrake- 106, is pivotally connected with one "extremity of a rod 108asshown at 109, the opin'to a groove 107 ,withwhich the outerpepositeextremityof the said rod 108 being pivotally connected to the bottom orbase of the frame work 7 2 as shown at 110. ,Therefore,-by virtue of theinstrumentahtles above recited, theitogglearms 96 and 97 act upon theband brake 106, through the instrumentality of the armature 60 and rod94, to prevent turningof the internal gear, during the upward movementof thesemaphorenrm.

As heretofore explained, when thesemaphore arm is caused to 'moveupwardly, the gear wheel 77 turns-in the direction of the arro3v seeFig, Now as soon as the gear wheel 77 has turned far enough to cause thepulley 73 to raise theisemaphorearm to the safety position, a projection111 with which the said gear wheel 77 is: provided,

comes into contact with the contact 5130f the circuit breaker 50 andacts upon the said contact 51 to separate the same from the opposingcontact lt), or the said circuit breaker.

50, whereby'the circuit is broken through the motor 48, since these twocontacts 49 and 50*serve to complete the motor ci.rcuit,j and of course,when they are separated from each other, the motor circuit will bebroken and the movement of the motor stopped. The electroanagnet -{lremains; energized while the semaphore armis in the raised positionandconsequently, the'toggle arms 96and 97,

are being acted. upon to tighten thebrake band 106 around the'internal"gear 86 for preventing movement of the latter, and thus, sincethe-internal gear 86 is prevented from turnlng the semaphore arm, isheld, or supported in the raised or safety position against theinfluence of gravity. In other words, in .order to allow the semaphoreto drop to a danger position, it is necessary to permit the internalgear 86, to, revolve and in order topermit the said internal gear torevolve it 1s necessary to breakthe c1rcu1t 'through the electro-magnet44, whereby the brake band 106 will be released from frictionalengagement with the said gear 86.

The operation of the mechanism to display the danger signals, when thecircuit is broken throughthe electro-magnet A l, Wll'l new be explained.Assummg that the train 57 is in'the block 14- and is travelinginfthe dircti on" of the arrow (see ,Fig. 4;) the current "from the source ofelectrical energy 20 willibe short circuited through thetrain 57 and therelay 23 denergized, whereby the core 30 willbe released and thecontactbar 81 allowed to fall into engagementqwith the co a ts 67.thua-breakiagthe cirouitthrough the green or safe light 88 and throughthe electro-magnet 44 and closing the'circuitthrough the red or dangerlight. 62,fthe latter condition being effected in the 1 following manner:The current from the source of electrical energy 84, may be said topassthrough the conductor 36 to a point 63, thence through a conductor 64,to the red or danger lamp 62-from whence it passes through conductor65,- contact 66, contact bar-'31, contact 67, conductor 68 and conductor34, to the opposite pole 35 of the source of electrical energy 34. Thebreaking ofv the circuit through the electro-magnet 44 results inreleasing the armature 60, whereby thebrake band 106 acts upon togglearms 96 and 97 under the influence of its tension to cause the saidtoggle arms to act upon the rod 94 to cause the latter to move thearmature 60 away from the magnet, thus releasing the brake band 106 fromfrictional engagement with-the internal gear wheel 86.

Since the frictional engagement of this brake:

band 106 with the internal gear 86, has been released the said internalgear will be permittedtorevolve and will be caused to re- 1ve'under theinfluence of the weight of the semaphore arm 61, by virtue of mechani'sm which will nowbe explained. The

downward movement of the semaphorearm 61 causes the pulley 73 to turn inthe direction opposite to the direction'indicated bythe arrow in Fig. 4,whereby the chain 1 7 4 is unwound from the said pulley 7 8. The

turning of the pulley 7 3 resulting from the doumward movement of thesemaphore arm 61 by virtue of'the chain'connection 74, the relativelylarge gear 77, will also be caused to revolve in the same'direction asthat of the pulley 73 or in other words, in the direction opposite tothe direction, indicated by the arrow in Fig. 4. Thismovementorrevolving of the relatively large gear "('7 acts upon the pinion 79,which as heretofore explained, is made fast to the sleeve 80, wherebythe said sleeve is causedto revolve upon'the shaft 82," which in turncarries the planetary gears, 84, therewith, the said planeta ry gears inturn acting upon the internal gear 86 to cause the latter to revolve.However, since the gear 89 is keyed or made.

fast upon theshaft 82 and since the vshaft '82 is locked againstmovement, in the manner which will later be describechthe planetarygears will be caused to travel around One side of the internal gear 86is provided with abeveled gear 113, which meshes with a pinion 114,mounted upon the'lower extremity of a governor shaft 115. Now therefore, when the gear 86 is revolving inthe manner "above explained, itwill impart movement to the governor shaft 115 through the medium of itspinion 114. This move.-

2 Inent', imparted to the governor shaft 115,

will act to prevent the rapid downward movementor suddenzdrop of thesemaphore arm 61 and thus prevent injury to the'mechanism resultingfromthe concussion orjar of the sudden drop ofthe semaphore arm 61.

The manner of controlling the drop orf downward movement ofthes'emaphore arm 61 will nowbeexplaijned. As'the governor shaft 115revolves 'theballs 116, of. the governor 104, will move outwardly andas-a re sult willlmove the collar 103-upwardly on the shaft'115. Thisupward movement of the collar 103 will result in bringingthe lug 101 ofthe arm 102' into "contact with :the extension to theftog' le arm [96whereby the toggle arm 96 will be-caused toturn upon its pivot 99andstraighten, out'orjbrin'g the two toggle'arms 96 and07'toward theiralined position resulting' in tightening the brake band 106 around theinternal gear 86 which prevents or retards the said gear from" revolvlngat too great a rate of speed The sald internal gear 86 actmg through itscon nection with the semaphore arm 61 in the a Y manner "heretoforeexplained toslacken or lessen the speed of the downward movementof thesemaphore arm 61.

Attention is here called to fact that therod94 and the rod 108arerespectively providedwith turnbuckles 11 7 and'1'18, in

r adjusting.

termediate their extremities fo the length ofthe afo'resaidj'rods.

Attention" is here called to]; the fact. that i the worm 91 will lockthe worm,.wheel 9O a'galnst movementf during the downward movement ofthe semaphore-arm andv since the c-rmfwheel' QO is made: fast; to theshaft 82 and thefge'ar 89. is also made fast to this shaft. '1 Boththeshaft:82 and the gear 89 will also be locked against movement. timesa resultthe planetary gear 84 must travel around and upon'the peripheryof the gear 89 without' actingto turn'the latter.

ihttention'is here called to the fact that in our improved mechanism thesafe and dan- 1 ger lights are not fin any way controlled by" thevmovement of the semaphore arm '61, but

are displayed aria; extinguished 'independ ently of the arm and themechanism for operating and controlling the saidarm; In v ew of thlsfact, if the semaphorearm or the mechanism,- for? operating the same, i7 should in anyway, become out of order, the

said arm wouldnot perform its function, the safe and danger lights wouldcontinue to be controlled andljlperform their. functions as a thoughthepsemaphore arm and its operating properly performing their mechanismwere i'iu'nctions. q

Attention is further 'calleditothe fact that the semaphore arm 61' iscounter-balanced and to accomplish this purpose the said arm I isprovided with a'counter balancing weight I 119, i which accomplishesthe' double purpose of acting to move the said arm downwardly and toserve as a shade or device for con cealing from view, the greenor' safelight 38, when the semaphore arm occupies the danger position. Thusifthe green light should, for any reason, fail to be EXtlIP'.
